Hi Bud,
I have the DMR-E80, and I'm very happy with it
It has an 80MB hard drive and the DVD-RAM. So I can record to HDD and then transfer to DVD-RAM.
I wish it did have Ethernet, because that way, I could just transfer my recordings via the net to my PC.
Now, I have to copy the recordings to my DVD-RAM, and then take them to the PC.
I think the way things are going, and prices on PCs and hardware are going down, I would just use the PVR and set up a system.
You could build yourself a MythTV (KnopMyth) system (Linux based)
http://www.mysettopbox.tv/knoppmyth.html and use your PVR-250.
However, the time base correctors and hardware encoder on the Panasonic DMRs are far better than the WinTV PVR.
I'm not sure about future models of Panasonic recorders, but I'm sure it's just a matter of time before they show up with a model that has some kind of network connectivity
